Title: Multilayer pipe
Inventor: MINAMI KOJI
IPC: C08G61/08
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To increase the resistance remarkably to a strong acid and also provide a superb mechanical strength and a high chemical resistance and further save on a manufacturing cost by making at least one layer a layer containing a polymer resin with an alicyclic structure, in the multilayer pipe with at least two or more layers. SOLUTION: The multilayer pipe is constructed of two or more layers including a layer containing a polymer resin with an alicyclic structure and another resin. The multilayer pipe 2 is, for example, of such a two-layer structure that a layer 4 containing the polymer resin with the alicyclic structure is formed on the innermost side and a layer 6 containing another resin is formed on the outermost side. The thickness of the layer 4 including the polymer resin with the alicyclic structure on the side which comes into contact with a chemical is made larger than the thickness of the layer 6 containing another resin on the outermost side. Thus it is possible to enhance the chemical resistance and the resistance to elution.  Consequently the multilayer pipe is preferably applicable for the transfer of a chemical especially in a semiconductor manufacturing process and the generation of rupture can well be suppressed even when the piping is structured of plural pieces of the multilayer pipe by connecting these pipes.

Abstract: PROBLEM TO BE SOLVED: To attain the reduction of the cost of a device by reproducing information while using the signal arithmetically generated from the delay quantity and the amplitude ratio of signal from the front and the rear of the advancing direction of a reproducing light beam eliminating a semiconductor beam for heating. SOLUTION: A repetition pattern of isolated recording marks separated by an extent twice with respect to the predicted value of the delay quantity β of risings of signals which are to be generated by magnetic domain wall movements from the front and the rear is recorded on a magneto-optical recording medium. A delay quantity detecting circuit 23 detects delay quantity β from the pulse interval between reproduced signals of the isolated recording mark pattern. An amplitude ratio detecting circuit 21 detects an amplitude ratio from amplitudes of adjacent reproduced pulses at the time of the isolated recording mark pattern. An arithmetic circuit 24 generates a summation Σ(-α)nh(t-nβ) based on the amplitude ratio and the delay quantity β.  An approximate signal 'B' with respect to a true reproduced signal is obtained by adding the summation to the signal 'A'=h(t) reproduced without the semiconductor beam for heating.
